[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[Lauda]

After your Primecoins mature, feel free to PM me with offers. Will pay for in BTC.  Nothing ridiculous though.  I'm not paying 0.01 BTC per XPM.  Looking for bulk purchase. 

It will be certainly more worth than 0.01btc.

At last! The dual Xeons have found their first block.

I have been mining with about 180 pps since 3 hours after the release (more than 24 hours now) but so far not got a single coin

Seems to be sheer luck at this point. I've been mining with 50pps for not even 24 hours and got a block within 5 hours of starting. But nothing since.

I have 5 i7-3770s and 2 i7-2600s mining, most with 3 cores. One of them running with 4 cores has gotten 8 blocks. The rest have gotten two and three, with one getting zero. All centos-6-based (x64).
My i5-2500k (at 3.3GHz) has gotten 5 blocks. ( Windows 8 ).
My Toshiba with an integraded AMD APU has gotten two blocks. No idea how. Mines very slowly. (Windows 8 again).
My 8350s have gotten no blocks at all. ( Windows 7 and Windows 8 )

My digitalocean tiny instances (any larger than tiny and they don't get performance worth the penny per hour) have gotten, out of 15 instances running for 6 hours, a whopping three blocks. However, being that each instance costs $0.007 (yes, less than a penny) per hour, and they've been running for around 8 hours, it's not bad. (Ubunt u10.04 x32)



Basically, i7-3770s are really good at mining, but luck is a crazy thing. AMD chips I have had little luck with, even though they do have high PPS. Cloud instances that are of any girth seem to provide very low hash rates. EC2 CPU XL provided around 24PPS with a max around 28PPS, at a cost of $0.50 per hour! No good.

Awful release of what could have been a nice coin.

- lack of nodes in OP
- lack of info in OP (diff change, blocks/hour, blockreward, etc)
- lack of mining-info in OP

Yeah, I know, we can figure it out... But not everyone is an experienced miner or wants to read a whole topic...

Why spend so much time on creating a new coin and blow it on the release?

I must have missed all that. Everything worked fine for me ("setgenerate true") and I felt more informed beforehand about this coin than any other; but I did read the prerelease thread thoroughly.

I'll put up one Bitcoin in bounty for a CPU-miner (standalone) that will run on both windows and linux and outperform the built-in miner.

Recompile the existing one with some more optimization flags or with the ICC compiler.

Anyone compiled a win64 optimized binary yet?

Yeah, at least going by primespersec figures, it did not give the boost that it did for scrypt.

[TheSpiral]

Lol, update from my rigs:
My i5-3570k has found 1 block since launch.
My ancient cheapo Athlon X2 BE-2300 has found 4 blocks. x___x
Need to get this up on my brother's computer :p

[blarg]

when does gpu mining come out?

found 4 blocks on my laptop ?!

[scootero1211]

when does gpu mining come out?

Is this something GPUs are good at? It's fundamentally different from hashcracking

It really depends on how well the programmer writes it.

[twobits]

Anyone compiled an OS X version yet (or got it running on OS X)?

Still has bitcoin icons in it though, anyone up to making a primecoin.icns file?

One thing that is nice about this coin is that it's making people think. You can't just auto/instamine, people with huge rigs don't have an advantage, cloud instances aren't that great for it, and ancient laptops are finding just as many blocks as current processors.  This is a far cry from almost every other alt-coin release out there, in that people are messing around with different compiling options trying to optimize it. It seems like this is how a new crypto launch *should* be. I'm proud to say I was there from the beginning

[ivanlabrie]

+1, I like where this is heading...or at least how it started.

[rbdrbd]

Hm...with one VM I have on a Xeon server:

Code:

local@cpuminer01site10:/$ /opt/coins/primecoin/primecoind getmininginfo
{
    "blocks" : 2889,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "primespersec" : 105,
    "pooledtx" : 0,
    "testnet" : false
}

And from an almost identical one (right next to it on the rack... about 1.5x more powerful, actually):

Code:

local@cpuminer02site10:~$ /opt/coins/primecoin/primecoind getmininginfo
{
    "blocks" : 2892,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "primespersec" : 2,
    "pooledtx" : 0,
    "testnet" : false
}

Notice, PPS on the first is 105 and on the second is 2.... any ideas what could cause this? Same binary....both VMs don't have crazy low CPU contraints/throttling (set up the same way), etc....the process is maxing out the CPU on both...

Made a simple high-res logo in Inkscape based off of the Bitcoin logo and the primecoin-qt icon.

The longest known Cunningham Chain has k=17.

So far the highest found by primecoin are 9 long in blocks 116, 1592, and 2044.

I got 8 active connections when I am in office.
But 31 connections at home.!

WHY? could anybody help me?

[starsoccer9]

Id be interested in buying a few of these coins once it gets up and going and someone has some

Also the devs can just kill the program?

[mustyoshi]

After compiling with optimization flags, a setgenerate true 1 on my stock i3 2120 is getting 80+ pps.
